Evolutionary Status of Selected Post-AGB Stars Based on Gaia DR3.

PARTHASARATHY M., KOUNKEL M. and STASSUN K.G.

Abstract (from CDS):

The evolutionary status of 24 post-AGB stars is presented based on Gaia DR3 data. All 24 stars have parallaxes accurate to better than 3σ and have RUWE values <1.4. Based on the Gaia DR3 distances the absolute luminosities are derived. For 14 of the stars, the luminosities confirm their post-AGB evolutionary stage. However, V1027 Cyg, which was previously classified as a post-AGB star, is found to have a higher luminosity than would be expected if it was truly a post-AGB star; thus it may be an evolved, massive, pulsating semi-regular variable star of type G7Ia. For 9 of the stars, the luminosities are lower than 1000 L⊙, indicating that some are post-HB stars and some are post-RGB stars.
